Whats goin on guys I swapped the filter and added Royal Purple Max ATF to my trans and after I did that when coming to a stop the shift from 2-1 sometimes sends a shudder through the whole truck and feels as if it might stall and it did it for the first time today! I don't know what the deal is it seems like the clutch might not be going in all the way. When I dropped the pan the were no shards and the metal on the magnet was so fine it was unreal. It's an 01 Dakota 4.7L 45RFE trans and 132000. it never did this until after the fluid and filter change any ideas would help alot.

 

Is this your first trans fluid change with the truck? Sometimes they say with that many miles, don't even bother changing the fluid if you haven't done it before. But sorry no answer on your problem.

 

you sure you used the correct fluid?

 

time for a rebuild...to many miles bad idea to change the fluid

 

The Synthetic might have caused this. Try adding in some lucas trans fix. (Swell the gaskets up.)

 

Yeah I know a rebuild will be in the near future so until then i'll give that lucas stuff a try. It really doesn't feel like the trans becuase it shifts so smooth, I'm leaning towards that it might be the torque converter.

 

i would personally never put any other fluid into the transmission other than mopar atf, and i dont agree with the "After so many miles " part with the fluid... still gets filtered until the point the filter is clogged to all hell and some particulates passing through actually damaging the tranny... the best one i got was " when you do a transmission fluid and filter change, half new fluid and half old and a new filter"... now if im not msitaken.. new filter.... old fluid... filters old fluid introducing filtered fluid to transmission, plugging up the filter requiring frequent filter changes... or you can just use a new filter with all new fluid and get the same results.... yeah

 

if you just dropped the pan you didnt get all the tranny fluid out. The fluid you added may not have mixed with the fluid left in the torque converter and could be causing problems. I would do a complete tranny flush and re-fill with the factory recommended fluid.

 

Flush? It all depends on what you want to do. Swelling Won't do anything but prolong any problems which you will have in the future. I could see a low level maybe doing this.

 

It honestly sounds like a fluid level problem to me.
